问题 I can't seem to figure out why this while loop stopped looping. It was doing fine before I moved some code around. Now I got something else working and it just doesn't loop. I've also tried making quit a bool set to true and tried to have it loop while it was true until the user hit 4 to exit in which case it would turn it to false but that didn't work.

CV'], $target_path)) { sleep(1); if (move_uploaded_file($_FILES['upload'][$first_name.' CV'], $target_path)) { echo "The file ".

So I need to modify the pulled date from the database by subtracting certain amounts of days. I have done this with different variables but I get some weird results which are not the ones I have specified. Am
